地质遗迹是黄河流域旅游资源供给体系的重要组成部分。运用平均最近邻、核密度估计和空间自相关等方法探究黄河流域1 481处重要地质遗迹的空间分布格局，建立黄河流域地质旅游开发潜力评价指标体系，借助熵权-TOPSIS模型深入探究黄河流域各市州盟的地质旅游开发潜力。结果表明：（1）黄河流域重要地质遗迹为集聚型分布，但不同类型和等级的地质遗迹集聚程度差异显著；（2）黄河流域地质遗迹整体呈中游稠密、上下游稀疏，一主双副、带状延伸的格局，黄河中下游晋豫交界地带是绝对的地质遗迹核心分布区；（3）全局尺度上正相关的集聚分布态势明显，但局部空间上不同类型、等级的地质遗迹空间关联特征差异显著；（4）黄河流域地质旅游开发潜力的空间分异和极化分布趋势明显，潜力高和较高的市州盟数量较少，潜力低和较低的市州盟约占46.09%，空间上呈现由黄河下游向上游梯度递减的格局。

Geological relics are an important part of the tourism resource supply system in the Yellow River Basin. The average nearest neighbor， kernel density estimation and spatial autocorrelation are used to explore the spatial distribution pattern of 1 481 important geological relics in the Yellow River Basin， and on the basis of which an evaluation index system for the development potential of geotourism in the Yellow River Basin is established， and with the help of entropy weight-TOPSIS model， the potential of geotourism development of the Yellow River Basin is deeply explored. The results show that： （1） The important geological relics in the Yellow River Basin are clustered， but there are significant differences in the degree of clustering of different types and grades of geological relics. （2） The geological relics in the Yellow River Basin as a whole show a pattern of "dense in the middle reaches， sparse in the upper and lower reaches， one main and two sub-mains， and a band-like extension"， and the Shanxi-Henan border zone in the middle and lower reaches of the Yellow River is the absolute core distribution area of geological relics. （3） The distribution trend of positively correlated agglomeration is obvious on the global scale， but the spatial correlation characteristics of geological relics of different types and grades differ significantly in local space. （4） The spatial differentiation and polarization distribution trend of the development potential of geotourism in the Yellow River Basin is obvious， with the number of cities with high potential and higher potential being relatively small， and the number of cities with low potential and lower potential accounting for 46.09%， and a gradient decreasing in the spatial distribution of geotourism potential from downstream to upstream， and a gradient increasing from downstream to upstream.
